OPEN-FIREPLACE WATER-HEATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 541,867, dated'J'uly 2, 1895. Application tiled March 3l, 1894 Serial No. 505 ,883. (No model.)

To all whom t may concern:

Be it known that we, SAMUEL H. MARTIN and WILLIAM H. .I ONES, citizens of the United States, residing at Lincoln, in the county of Logan and State of Illinois, have invented a new and useful OpenFirepiace Water-Heating Apparatus, of which the following is a specification.

This invention relates to open lire-place water heating apparatus; and it has for its ohject to effect certain improvements in open tire-places whereby the heat generated on the grate therein shall be more completely utilized than heretofore.

To this end the main and primary object of the present invention is to provide a new and useful fire back or lining for open fireplaces in connection with several other features of construction whereby the fire-places shall beutilized for the heating of a building by either steam or hot watercirculation.

W'ith these and other objects in view which will readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated and claimed.

In the accompanying drawings, Figure l is a front elevation of an open fireplace equipped with the herein described improvements, showing the sliding "airtight front door dropped to its lowest position, and showing in dotted lines theposition of the door when closed. Fig. 2 is a similar view on a small scale showing the air-tight front door adjusted to a position to bank the lire and to provide for the ventilation of the room. Fig. 3 is an enlarged vertical sectional view of the replace. Fig. 4 is a horizontal sectional view on the line a: a: of Fig. 3. Fig. 5 is a similar `view on the line y y of Fig. 3.- Fig. Gis a detail plan View of the re-grate. Fig. 7 is a detail View showing more clearly theconnection of the connecting basins. Fig. 8 is a perspective view of the heating apparatus removed from the fireplace.

Referring to the accompanying drawings,

l designates an ordinary open fire place formed in the wall of a building inthe usual manner and from the top of which leads the ordinary chimney iiue 2. The open tire place 1, is provided with the ordinary equipment at the front of the wall, and in the present invention theV inner side and back Walls of the Iireplace are adapted to be faced with the sheet metal lining 3, that conforms to the interior configuration or contour ofthe fireplace and extends to the-front edges of the front opening of the fireplace, and said sheet metal lining 3 is provided at the top with the flue opening 4:, that opens into the chimney iue 2. This lining 3, may be properly termed the outside lining of the fireplace attachments as it is intended to more thoroughly confine the heat and protect the interior heater devices that form the main tire back or lining for the replaee. l

At the usual pointwhere the grateis located, the openV fireplace accommodates therein the fire grate 5. j The tire grate 5 preferably and essentially consists of the outer rectangular grate section 6, provided with a central opening 7, and a central dumping grate section 8, that is adaptedV towork inside of the opening 7 of the section The central dumping grate section 8 'that works inside ot'` the grate section 6 is mounted at its opposite ends on the usual journals 10.

The back and sidewalls of the open fireplace are lined with a series of vertical heating tubes 14 and 14, respectively. The vertical heating tubes 14 and 14a, are arranged reasonably close together at the sides and back of the fireplace to form the side and back walls thereof directly next to the grate, which is inclosed in the space confined between the lower ends of the side and back series of these vertical heatng tubes, in contact with which the heat from the fire directly comes in order to secure a thorough and rapid heating of the Water that circulates therein. .The said ver-v tical heating tubes let and 14:, are constructed in a substantially triangular shape in order to present the greatest possible surface to the heat, and at their front tsides are provided with the longitudinal heat grooves 15, and at their corresponding rear sides with the vertical or longitudinal pipe grooves 16, the function of which latter grooves will be more particularly referred to, but it will be obvious that the front grooves l5 of the heating tubes greatly increase the heating area thereof. The back seriesofvertical heating tubes 14E or those located at opposite sides ofy the iireplace, and have projected from their upper ends the forwardly and upwardly disposed crown portions or crown tubes 17, that extend directly over the fire so as to interrupt the direct upper passage'of the heat and thereby secure a greater utilization thereof.

The upper extremities of the forwardly and upwardly disposed crown tubes 17 have connected thereto the lower ends of a series of short connecting pipes 18, the upper ends of which lead into the bottom of a hot water box 'or reservoir 19. The hot water box or reservoir 19, is arranged within the open fireplace at the top thereof, and at one side of the chimney `flue, and has connected theretothe flow pipes 20, that are designed to carry hot water or steam to the radiators arranged throughout the house.

The side series of vertical heating tubes 14a, extend to points slightly above the inclined crown portions or tubes 17, and are connected at their upper ends to opposite ends of the inclined heating box 21 and the longest of the tubes 14a are connected at their upper ends to the box or reservoir 19, as clearly illus trated in Fig. 8 0f the drawings. The inclined heating box 21, is -arranged directly over the top of the crown tubes 17, and receives the heating effect from the heat that passes between the said cr'own tubes, and also serves as a; deiiector to deflect the heat forwardly and upwardly before it can escape out of the chimney iue. The said inclined heat` ing box 21, is entirely inclosed to confine the circulating water which rims therein fromthe side tubes 14a, and has connected to the closed upper end thereof aseries of connecting pipes `22, the upper ends of which connect with the rear sides of the hot water box or reservoir 19.

The front heatgrooves 15, of all of the vertical heating tubes extend the full length thereof, and in the back series of heating tubes 14 these grooves are continued throughout the length of the crown Aportions or tubes 17, so as to secure the heating eifect of the heat tothe greatest possible extent in order that there maybe no waste heat, andthe longitudinal pipe grooves 16 at the rear sides of the heating tubes are adapted to accommodate therein one side of the vertical feed pipes 2 3, and the upper ends of said feed pipes are coupled into thelower sides of the rectangular water ring 24, that encircles the inside of the iireplace at an intermediate point and has connected to the opposite front ends Vthereof the upper ends of the return pipes 25, to which pipes 25 are coupled the return circulating pipes 26, that return the water or steam from the radiators into the return pipes 25, that are arranged vertically at opposite front sides of the open fireplace.

The feed water which enters the return pipes 25, the rectangular water ring 24 and the feed pipes 23, is necessarily subjected to the heating action of the tire within the iire place before reaching the vertical heating tubes, and the lower ends of the vertical feed pipes 23, alongside of the vertical heating tubes, are coupled to the lower ends of said tubes by the connectingbasins 27. The basins 27 are connected directly to the lower ends of the pipes 23 and to the lower ends of the tubes 14 and 14a, by means of the small coupling or connecting nipples 28, that prevent the cold or feed water from entering the heating tubes as rapidly as the hot water passes from said tubes into the box or reservoir 19, thereby causing a forced circulation or suction in the return pipes, whereby rooms on the same floor as the open fireplace or grate may be heated as successfully as rooms above the same. The said basins 27,are each provided with bottom pet or drain cocks 29, for draining the heating tubes of sediment, &c., at any time desired.

. In order to'increase the circulation of wateror steam and to provide for a more complete utilization thereof a series of partitioned drop tubes 30 are connected at their upper'ends to the bottom of the hot water box or reservoir 19 by means of separate nipples 31, the water entering the tubes through one of these nipples and circulating out of the same through the other nipple, andin order to properly control the draft of heat and to direct the same to different parts of the apparatus a regulator damper 32, is pivotally mounted within the open fireplace directly within the lower end of the chimney flue 2. By turning this damper to one side or the other of the chimney iiue, it will be obvious that the heat will be caused to circulate either throughout the front or rear portion of the fireplace heater just described, and which forms a fire back or water lining for the grate.

In connection with the tire back heating apparatus is employed a sliding air-tight front The front door 33 is made of a t to slide at its opposite edges in suitablel guides 34, at opposite front sides of the lireplace, and said door is of a size sufficient IIO to entirely inclose the front opening of the two sets or series of these openings, in one set or series of which there is a less number of openings to provide for the banking of the tire at night as shown in Fig. 2 of the drawings. Opposite weight chains 36, are connected at one end to opposite top edges of the door 33 and passing over suitably arranged guide pulleys 37, are connected at the other ends to balancing weights 38, working within opposite inner sides of the fireplace to provide for balancing the door. By lowering the door entirely below the grate line the tireplace may be used in the ordinary manner as shown in Fig. l.

By adjusting the door to the position shown in Fig. 2, the fire is banked by cutting ott' the direct and main draft while atop Ventilating opening cc, is left to allow impure air to pass out into the chimney, and by closing the door as shown in dotted lines in Fig. 1, the direct draft is given to the fire, and the door then acts as a blower, thereby transforming the open fireplace substantially into a furnace heater, and confining all the heat onto the heating apparatus that forms the fire back or lining for the fireplace.

Changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described the invention, what is claimed, and desired to be secured by Letters Patent, is-

l. In a heater of the class described, a series of upright heating tubes adapted to be arranged within an open fireplace, a hot water box or reservoir adapted to be arranged within the top of an open fireplace and connected t with the upper ends of said tubes, a rectanguiar water rin g adapted to encircle said tubes and connected with the lower ends thereof, and return pipe connections with saidwater ring, substantially as' set forth.
